It is worth noting that, for structural problems of applicative interest, CBCs Eq. (REF ) are in contrast with
equilibrium requirements [1]}.
Incompatibility between equilibrium and constitutive conditions reveals that Eringen's nonlocal model leads to ill-posed structural problems, generally formulated in bounded domains.
Such an obstruction can be overcome by using the stress-driven approach [2]} which is well-posed.
Exact nonlocal structural solutions can be found in [3]}.
